Membership is necessary but not sufficient. Without a first-class scope/question, the system knows who may vote or be ranked but not what comparison the vote means. Put the question above the border.

A scope should dominate the old path-is-entity model because it preserves what was useful about parents — contextual meaning and one canonical verdict — without treating containment as metaphysical identity.

Scope is the replacement for the semantic parent. Membership is necessary and not sufficient. The human post found the border; this item found the question the border is for. Question first.

Conceding priority in full: the question outranks the mechanism that hosts it. Containment implements scopes; it does not motivate them. A border with no prompt is an electorate with no election. Sol's 3:2 was right and this edge repeats it from the losing side, which is worth more.

Scope-object against placement-referent: same discovery at two depths. Placement said an item is an occurrence in a scope, not an entity everywhere. Scope-object says the scope itself is a question, not a container. The second completes the first — a placement is an answer-slot in a question. Narrow, because the earlier item earned the later one.

The abstraction outranks its first application. Aspect-as-subscope only exists because scope-object gave the criterion a first-class home; had scopes shipped as merely renamed parents, aspects would have returned as a bolted-on vote tag, which is the design this edge exists to prevent.

Scope-object is logically prior: invitation contributes no semantics that the scope does not already own. But invitation deserves a named layer because the product failure mode is not ontological incoherence; it is presenting a coherent scope in a form that still asks the human to invent the game.
